DEVICE ON COTTON FRAMES FOR THE PRODUCTION OF BODILY THICKEN IN GS 01? PATTERNS.

Application filed March 9, 1927, Serial No.

This invention relates to a device which makes it possible, to work bodily thickened patterns, especially leaf-shaped ones, into stockings as lengthened heel-reinforcement on the cotton-frame. It has been proposed to provide at this point of the stocking some little pattern by giving a dented shape to the boundary lines of the reinforcement, but patterns in leaf-shape and the like could hitherto not be obtained for the reason, that it was impossible to produce the re-entering cor- .ners and arcs.

The device according to the invention is shown, by way of example, in the accompanying drawing in Figs. 1 and 2 in front elevation mounted on one side of a cotton frame respectively in the position of rest and in the working position.

Fig. 3 is a side elevation of Fig. 2. Fig. 4 shows a portion of a patternwvheel with a thread-guide on larger scale.

Fig. 5 shows the finished portion of the stocking as it comes from the frame.

The commonly used abutment for the threaduide is put out of working and consequent y not shown in the drawing. For it is substituted a large pattern-wheel 1 having tappets, one pattern-wheel being rotatably mounted on each end of the cotton frame, so that the tappets 2 project towards the centre of the frame. As the pattern is composed of two portions I, II (Fi 5), four thread guides 3 to 6 are provided besides the guides 7 and 8 for the base threads, and three ofthese thread guides cooperate with the tappets on the left-side of the frame, the three others co-operating with the ta pets of the pattern wheel at the right side 0 the frame.

In order that the lappets correctly limit the movements of the thread-guides the heads 9 on the tappets of the pattern-wheels are longer or shorter according to the pat- 4 tern, so that they stand more or less distant from the pattern Wheel, the thread-guide bars coming into contact with said heads 9. Each pattern wheel 1 is rotated one division after the knitting of one or several rows of loops and in order that the heads 9 ive way un er the stroke of the thread-gui e bars 3 to 8, the attern-wheel 1 must be raised, when another tappet-head has to come in front of the thread guide-bar. The rotating 0 the pattern-wheel is effected, uniformly .aside the eccentric 12 in order 173,943, and in Germany December 1, 1926.

through one division, by means of a ratchet l0 and pawl 11. The engaging and disengaging of the eccentric 12, which raises the pattern wheel from the main shaft 13, is controlled from a pattern chain let which, at its two ends is mounted on the lower portion of the machine and which, when travelling, brings pattern-buttons 15 under a lever 16. The lever 16 is thus lifted, so that it pulls that it ets underneath a roller 17 mounted on a ro l8 and causes the rising of the pattern-Wheel whilst, when no button 15 of the pattern chain stands under the lever 16, this lever remains in the lowered position, the eccentric 12 under the roller 17 of rod 18 being pushed aside (Fig. 1) and does no longer act upon the pattern wheel. The pattern wheel executes every time only a part rotation, when the thickening from A to B (Fig. 5) is being produced and this according to the pattern, the pattern-wheel being raised every time and lowered by gravity.

At the production of the pattern (Fig. 5) the rotation begins at the beginning of the thickening pattern at A and after one or two rows of loops have been knitted, the pattern-wheel is rotated and raised and brings another tappet-head in front of the guide of the thickening thread, which is operated in the well known manner. \Vhcn the thickening has been produced up to the point a: a second thread guide is engaged for producing a thickening, and both thread-guides lind their tappcts on the pattern-wheel which. after every row ofloops, is rotated and raised in order to bring into position as abutment for the thread-guidc-bars those tappets, which correspond to the pattern. The one thickening threadguidc produces the thickened edge-portion from a: to y and the second thickening thread-guide produces the inner portion m. After the pattern has been completed up to y the see- 0nd thickening thrcadguide is disengaged up to a, to be engaged again for producing the point a. When the point z is finished the second thread-guide is disengaged and the curve-portion is produced by the first thickening-thread-guide up to the heel-portions with rotation and raising of the pattern-wheel. From this moment. when the heel-thickening has been finished the thickening ceases and the base-thread-guide knits in the well known manner the toe and leg of the be substituted which carries 15 the pattern proyccting from the inner surface of each pattern-wheel and serving as abutments for said tliickening-thread-guides, a pattern-chain controlled by said eccentric, means for raising said pattern wheel prior to each part rotation and means for communicating a part rotation to said patternwhcel after the knitting of one or two rows of loops in order to bring said pattern wheel out of the range of said thread-guidebars, so that it descends again by gravity to serve as abutment.

in testimony whereof I affix my signature.
